Business Overview

We are a clinical stage biotechnology company developing new treatments for life threatening conditions by improving the body’s ability to bring oxygen to the areas where it is needed most. We are developing our lead product candidate, transcrocetinate sodium, also known as trans sodium crocetinate (“TSC”), for use in those life-threatening conditions in which cellular oxygen deprivation (“hypoxia”) is the basis for significant unmet medical needs. TSC is designed to safely and selectively target and re-oxygenate the micro-environment of hypoxic cells, and can potentially be used in many indications, including stroke, oncology, multiple organ failure and cardiovascular disease. In stroke, TSC helps promote the diffusion of oxygen into those brain cells in which oxygen-deprivation causes neuronal death resulting in patient mortality or morbidity. In cancer, TSC re-oxygenates treatment-resistant cancerous tissue, making the cancer cells up to three times more susceptible to the therapeutic effects of standard-of-care radiation therapy and chemotherapy. In multiple organ failure, we have begun a cooperative research effort with University of Virginia Health (UVA) and the Integrated Translational Research Institute of Virginia (iTHRIV), to evaluate TSC in patients with Acute Respiratory Distress Syndrome (ARDS) associated with COVID-19 infection. iTHRIV is a National Institutes of Health (NIH)-funded Clinical and Translational Awards (CTSA) program.

A range of tissue types, including both normal and cancerous cells, has been shown to be safely re-oxygenated in our preclinical and clinical studies using TSC’s novel mechanism of action. We believe TSC’s ability to re-oxygenate normal (i.e. non-cancerous) tissue that has become oxygen-deprived provides opportunities for new therapeutic approaches to conditions ranging from stroke and emergency medicine - including multiple organ failure associated with Acute Respiratory Distress Syndrome (ARDS) - to cardiovascular and neurodegenerative diseases. In the treatment of cancerous tissue, we believe TSC’s therapeutic potential to lessen the tumors treatment resistance to radiation and chemo-therapy is not limited to one specific tumor type, thereby making it potentially useful to improve standard-of-care treatments in many life-threatening cancers. Given TSC's safety profile and animal data, we could, with appropriate funding, move directly into Phase 2 studies for TSC in other cancers. The successful completion of trials for TSC or any other potential product candidate in these or any other indication is dependent upon our ability to further raise necessary capital.

We believe that TSC has potential applications in stroke and emergency medicine. In stroke, a Phase 2 trial in cooperation with the University of California Los Angeles (UCLA) and the University of Virginia (UVA) to test TSC in the treatment of acute ischemic or hemorrhagic stroke is currently enrolling patients. Stroke is the 5th leading cause of death in the U.S. and the No. 1 cause of adult disability. Our stroke trial, which features in-ambulance dosing of TSC, is named the “PreHospital Acute Stroke Therapy - TSC” (PHAST - TSC) study, and is expected to enroll 160 patients, with 80 in the treatment arm and 80 in the control arm. We believe in-ambulance dosing of TSC will significantly cut the time in which the stroke-related oxygen deprivation to brain cells goes untreated, potentially leading to a better outcome for stroke victims treated in this manner. Near term enrollment in this trial is expected to be minimal for the duration of the COVID-19 pandemic.

Patients with COVID-19 infections are at risk for developing ARDS, which can lead to death from systemic hypoxemia (general lack of oxygen to body tissue and vital organs). We, along with researchers affiliated with UVA and iTHRIV, believe the oxygen-enhancing mechanism of action of TSC could benefit COVID-19 patients by mitigating the multiple organ failure that often accompanies systemic hypoxemia, and are, together, exploring avenues to advance TSC’s development as quickly as possible for this use. Preclinical data indicate TSC increases oxygen availability in animal models of acute lung injury, mitigating the negative effects of systemic hypoxemia. Preclinical publications also indicate TSC’s ability to mitigate systemic hypoxemia in other animal models, including hemorrhagic shock. Clinical data from 150 patients receiving TSC for other indications demonstrate that the drug has an acceptable safety profile in both healthy and critically ill patients.

We, together with UVA/iTHRIV, have engaged in initial discussions with the U.S. Food and Drug Administration (FDA) to assess possible regulatory pathways for the evaluation of TSC in ARDS-related COVID-19 patients.

Our oncology program targets TSC against treatment-resistant brain cancer. A Phase 2 clinical program, completed in the second quarter of 2015, evaluated 59 patients with newly diagnosed glioblastoma multiforme (“GBM”), a particularly deadly form of primary brain cancer. GBM affects approximately 12,000 patients annually in the United States and approximately 35,000 patients annually worldwide. This open label, historically controlled study demonstrated a favorable safety and efficacy profile for TSC when combined with GBM’s standard of care, including a 37% improvement in overall survival over the control group at two years. A particularly strong efficacy signal was seen in the inoperable patients, where survival of TSC-treated patients at two years was increased by almost four-fold over the controls. In December 2017, we initiated the INvestigation of TSC Against Cancerous Tumors (INTACT) Phase 3 trial in the newly diagnosed inoperable GBM patient population. The trial is designed to enroll 236 patients in total, with 118 in the treatment arm and 118 in the control arm.

The trial began with an FDA-mandated open label 8 patient safety run-in for which enrollment has completed and is now closed. With the FDA’s permission, a total of 19 patients were enrolled to ensure that at least 8 complete data sets meeting the FDA’s specified 4-month exposure period would be available for review. The INTACT Trial Data Safety Monitoring Board (DSMB) met in the third quarter of 2019 and, based on their analysis, recommended that the study be continued. The DSMB concluded that no adverse safety signal had been observed, and unanimously recommended continuing the study as planned using the highest tested dose of TSC - 1.5 mg/kg - during the adjuvant treatment chemotherapy period with temozolomide. We believe that a preliminary efficacy signal was also received. A total of 10 patients were enrolled into the higher dose cohorts and 9 in the lower dose cohorts. In the higher dose patients, where the best results were expected, 3 discontinued treatment before meeting the FDA exposure period criteria. Of the 7 patients who met the criteria, 5 remain alive as of March 12, 2020. Commencement of enrollment in the randomization portion of the INTACT Phase 3 Trial is contingent upon our entering into a strategic partnership providing the necessary resources to undertake the full trial.

In addition to the TSC programs, we are exploring alternatives regarding how best to capitalize upon our product candidate RES-529, which may include possible out-licensing and other options. RES-529 is a novel PI3K/Akt/mTOR pathway inhibitor which has completed two Phase 1 clinical trials for age-related macular degeneration and was in preclinical development in oncology, specifically GBM. RES-529 has shown activity in both in vitro and in vivo glioblastoma animal models and has been demonstrated to be orally bioavailable and capable of crossing the blood brain barrier.

COVID-19 Pandemic

The spread of COVID-19 during 2020 has caused an economic downturn on a global scale, as well as significant volatility in the financial markets. In March 2020 the World Health Organization declared COVID-19 a pandemic. As of May 11, 2020, we have experienced some disruptions to clinical operations, including with respect to patient enrollment in our clinical trials. In this time of uncertainty as a result of the COVID-19 pandemic, we are continuing to conduct trials at certain clinical trial sites while taking precautions to provide a safe work environment for our trial participants and employees. However, some in-person visits are currently on hold and other activities are being conducted remotely to the extent possible. We have also made internal resource allocation decisions in order to deliver on key business objectives and to increase our financial flexibility, including, for example, by pausing the development of certain preclinical research programs, delaying the start of certain longer-term clinical studies, limiting staff hiring and reducing the number of contract workers, and delaying or limiting information technology and facilities infrastructure projects. We may have to take further actions that we determine are in the best interests of our trial participants and employees or as required by federal, state, or local authorities.

As the pandemic continues to unfold, the extent of the pandemic’s effect on our operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include changes in the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, and the resumption of widespread economic activity. Any prolonged material disruption on recruiting or retaining patients in our clinical trials, the ability of our suppliers to provide materials for our product candidates, or the regulatory review process could cause additional delays with respect to product development activities and could negatively impact our consolidated financial position, consolidated results of operations and consolidated cash flows.

Financial Summary

As of March 31, 2020, we had cash and cash equivalents of $10.8 million. We have incurred operating losses since inception, have not generated any product sales revenue and have not achieved profitable operations. We incurred a net loss of $2.6 million for the three months ended March 31, 2020. Our accumulated deficit as of March 31, 2020 was $94.3 million, and we expect to continue to incur substantial losses in future periods. We anticipate that our operating expenses will increase as we continue to advance our lead, clinical-stage product candidate, TSC. We anticipate that our expenses will substantially increase as we:

      We intend to use our existing cash and cash equivalents for working capital and to fund the research and development of TSC. We believe that our cash and cash equivalents as of March 31, 2020, along with the $4.8 million in proceeds received in the second quarter of 2020 related to warrant exercises, will enable us to fund our operating expenses and capital expenditure requirements (including our clinical trials) into the third quarter of 2021.

Financial Operations Overview

Revenues

We have not yet generated any revenue from product sales. We do not expect to generate revenue from product sales for the foreseeable future.

Research and Development Expense

Research and development costs include, but are not limited to, third-party contract research arrangements, employee-related expenses, including salaries, benefits, stock-based compensation and travel expense reimbursement. Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As we advance our product candidates, we expect the amount of research and development costs will continue to increase for the foreseeable future. Research and development costs are charged to expense as incurred.

General and Administrative Expense

General and administrative expenses consist principally of salaries and related costs for executive and other personnel, including stock-based compensation, expenses associated with investment bank and other financial advisory services, and travel expenses. Other general and administrative expenses include professional fees, facility-related costs, communication expenses and professional fees for legal, patent prosecution and maintenance, and consulting and accounting services.

Interest Income

Interest income is interest earned from our cash and cash equivalents.

Income Tax Benefit

We recognize income tax benefit to utilize indefinite deferred tax liabilities as a source of income against indefinite lived portions of the Company’s deferred tax assets.

Results of Operations for Three Months Ended March 31, 2020 Compared to Three Months Ended March 31, 2019

The following table sets forth our results of operations for the three months ended March 31, 2020, and 2019.

We recognized $1.5 million in research and development expenses during the three months ended March 31, 2020 compared to $1.7 million during the three months ended March 31, 2019. The decrease in research and development expense was mainly attributable to a $0.4 million decrease in expense related to our Phase 3 GBM trial. The lead-in portion of the Phase 3 GBM trial was completed in the fourth quarter of 2019. This decrease was offset by a $0.1 million increase in manufacturing costs and an increase of $0.1 million in expense related to our Phase 2 stroke trial.

General and administrative expenses increased by $0.2 million during the three months ended March 31, 2020 compared to the three months ended March 31, 2019, mainly due to an increase in professional fees and salaries and wages.

The increase in interest income for the three months ended March 31, 2020 compared to the three months ended March 31, 2019 is primarily attributable to having a larger cash and cash equivalents balance earning more interest during the three months ended March 31, 2020 compared to the three months ended March 31, 2019.

We recognized income tax benefit of $0.4 million and $0.2 million during the three months ended March 31, 2020 and 2019, respectively, to reflect the utilization of indefinite deferred tax liabilities as a source of income against indefinite lived portions of the our deferred tax assets.

Liquidity and Capital Resources

Working Capital

To date, we have funded our operations primarily through the sale and issuance of preferred stock, common stock and convertible promissory notes. As of March 31, 2020, we had $10.8 million in cash and cash equivalents, working capital of $10.4 million and an accumulated deficit of $94.3 million. We expect to continue to incur net losses for the foreseeable future. We intend to use our existing cash and cash equivalents to fund our working capital and research and development of our product candidates.

 Cash Flows

The following table sets forth our cash flows for the three months ended March 31, 2020 and 2019:

Operating Activities

Net cash used in operating activities of $3.5 million during the three months ended March 31, 2020 was primarily attributable to our net loss of $2.6 million, our net change in operating assets and liabilities of $0.8 million and our change in deferred income taxes of $0.4 million. This amount was offset by $0.2 million in stock-based compensation expense and depreciation expense. The net change in our operating assets and liabilities is primarily attributable to a decrease in our accounts payable and accrued expenses due to the timing of our payments to our vendors and employees as well as an increase in our prepaid expenses, deposits and other current assets.

Net cash used in operating activities of $2.7 million during the three months ended March 31, 2019 was primarily attributable to our net loss of $2.7 million and our change in deferred income taxes of $0.2 million. This amount was offset by our net change in operating assets and liabilities of $0.1 million and $0.1 million in stock-based compensation expense and depreciation expense. The net change in our operating assets and liabilities is primarily attributable to an increase in our accounts payable and accrued expenses due to the timing of our payments to our vendors, slightly offset by an increase in our prepaid expenses, deposits and other current assets.

Financing Activities

Net cash provided by financing activities was $0.2 million during the three months ended March 31, 2020, which was attributable to the $0.4 million in proceeds received from the exercise of common stock warrants, offset by approximately $0.2 million in payments for offering costs.

We had no financing activities during the three months ended March 31, 2019.

Capital Requirements

We expect to continue to incur substantial expenses and generate significant operating losses as we continue to pursue our business strategy of developing our lead product candidate, TSC, for use in the treatment of ARDS, stroke, GBM, and other hypoxia related indications. Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts of cash to advance the clinical development of our product candidates. At the current time, the bulk of our cash resources for clinical development is dedicated to the Phase 2 trial for TSC in acute stroke, and if approved by the FDA, clinical work for TSC in the treatment of ARDS in COVID-19 patients. While we believe we have adequate cash resources to continue operations into the third quarter of 2021, we will need to raise additional funds in order to complete these trials. We do not expect to commence any clinical trials beyond these trials unless we are able to raise additional capital, enter into strategic collaborations, or make alternative financing arrangements for any such trials. To date, we have funded our ongoing business operations and short-term liquidity needs, primarily through the sale and issuance of preferred stock, common stock and convertible debt. We expect to continue this practice for the foreseeable future, however, we may enter into strategic partnerships or transactions in order to fund our ongoing capital requirements.

As of March 31, 2020, we did not have credit facilities under which we could borrow funds or any other sources of committed capital. We will seek to raise additional funds through various sources, such as equity and debt financings, or through strategic collaborations or licensing agreements. We can give no assurances that we will be able to secure additional sources of funds to support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or be on terms acceptable to us, or that potential delays in clinical trials due to the impact of COVID-19 could increase the anticipated cost of completing our clinical trials. This risk may increase if economic and market conditions deteriorate. If we are unable to obtain additional financing when needed, we may need to terminate, significantly modify or delay the development of our product candidates and our operations, or we may need to obtain funds through collaborators that may require us to relinquish rights to our technologies or product candidates that we might otherwise seek to develop or commercialize independently. If we are unable to raise any additional capital in the near-term and/or we cannot significantly reduce our expenses and are forced to terminate our operations, investors may experience a complete loss of their investment.

To the extent that we raise additional capital through the sale of our common stock, the interests of our current stockholders may be diluted. Also, the Company’s outstanding warrants, if exercised, or any future warrants, if exercised, will dilute the interests of our current stockholders. If we issue preferred stock, or convertible debt securities, it could affect the rights of our common stockholders or reduce the value of our common stock or any outstanding classes of preferred stock. In particular, specific rights granted to future holders of preferred stock or convertible debt securities may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined by the rules and regulations of the SEC that have or are reasonably likely to have a material effect on our financial condition, changes in financial condition, revenue or expenses, results of operations, liquidity, capital expenditures or capital resources. As a result, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these arrangements.

Critical Accounting Policies

The Critical Accounting Policies included in our Form 10-K for the year ended December 31, 2019, filed with the SEC pursuant to Section 13 or 15(d) under the Securities Act on March 17, 2020 have not changed.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) that are designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and we are required to apply our judgment in evaluating the cost-benefit relationship of possible internal controls. Our management evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered in this report. Based on that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of such period to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

Change in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the quarter ended March 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

For this item, please refer to Note 7, Commitments and Contingencies to the Notes to the Unaudited Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated herein by reference.

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, Item IA - "Risk Factors," in our Annual Report on Form 10-K for the year ended December 31, 2019, which could materially affect our business, financial condition or future results.

Events outside of our control, including public health crises such as the COVID-19 pandemic, could negatively affect our business and our operating results.

The novel coronavirus (“COVID-19”) pandemic has resulted in significant financial market volatility, and its impact on the global economy and our operations remains uncertain. A continuation or worsening of the pandemic could have a material adverse impact on our business, results of operations and financial condition and on the market price of our common stock.

On March 12, 2020, the World Health Organization declared COVID-19 to be a pandemic. In an effort to contain and mitigate the spread of COVID-19, many countries worldwide have imposed quarantines, business closures and unprecedented restrictions on travel. The outbreak and government measures taken in response, have had a significant impact, both direct and indirect, on economic activity, as worker shortages have occurred, supply chains have been disrupted, facilities and production have been suspended and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services has fallen.

As a result of the COVID-19 pandemic, we may experience disruptions that could severely impact our business and clinical trials, including:

Any negative impact that the COVID-19 pandemic has on recruiting or retaining patients in our clinical trials, the ability of our suppliers to provide materials for our product candidates, or the regulatory review process could cause additional delays with respect to product development activities, which could materially and adversely affect our ability to obtain regulatory approval for and to commercialize our product candidates, increase our operating expenses, affect our ability to raise additional capital, and have a material adverse effect on our financial results. In addition, our clinical trial patients who contract COVID-19 may have adverse health outcomes that could impact the results of our clinical trials.

The COVID-19 pandemic has resulted in significant financial market volatility and uncertainty in recent weeks and continues to rapidly evolve. The extent to which the outbreak impacts our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new information that may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others. A continuation or worsening of the levels of market disruption and volatility seen in the recent past could have an adverse effect on our ability to access capital, on our business, results of operations and financial condition, and on the market price of our common stock.

We face risks related to the planned clinical program to test TSC as a treatment for COVID-19, which has not been approved by the FDA or any other regulatory authority.

In response to the recent global outbreak of COVID-19, on April 24, 2020, we submitted a Pre-Investigational New Drug Application (Pre-IND) to the FDA related to a planned clinical program using TSC in COVID-19 patients displaying severe respiratory symptoms and low oxygen levels. Under federal regulations, the FDA has up to 60 days to hold an advisory meeting with us, but for COVID-19-related submissions, the FDA has notified us of its intention to accelerate its review of the Pre-IND submission under its Coronavirus Treatment Acceleration Program. Clinical trial start-up preparations are continuing as we await the FDA’s response. The estimated timing of regulatory approval is based on factors beyond our control, including but not limited to, unforeseen scheduling difficulties and unfavorable results at various stages in the pre-market application process. This FDA approval or clearance process may be time-consuming and costly. Moreover, there is no guarantee that the pre-IND submission will ultimately be acceptable to the FDA for an IND submission or that the FDA will not require significant changes that might take significant time to implement, if at all, or that any such required changes will be financially feasible for the Company. Even if the Pre-IND or a revised protocol is acceptable to the FDA for an IND submission, there can be no assurance as to when the FDA might provide such guidance or when the program might be able to commence, if at all. We intend to work closely with the FDA to determine the best path forward to obtain approval, but we cannot guarantee that these efforts will be successful. Even if FDA approval for trials evaluating TSC for the treatment of ARDS is ultimately granted and we are able to move forward with clinical trials, such trials may entail significant additional time, effort and expense, particularly in light of the difficulty of doing business during the COVID-19 pandemic. In addition, there is no assurance of favorable results from any clinical trials, or that one or more of such trials will be completed in the currently anticipated timelines or at all. Further, we may make a strategic decision to discontinue clinical testing of TSC in COVID-19 patients, including in the event that other parties are successful in developing a more effective treatment for COVID-19.

We have committed significant capital and resources to begin funding and supplying the clinical trials for the COVID-19 program. If we are unable to obtain regulatory approvals, or if clinical trials fail to demonstrate the clinical safety profile or the efficacy of TSC for the treatment of ARDS in COVID-19 patients, or if we make a strategic decision to discontinue testing TSC as a treatment for COVID-19 patients, we will be unable to recoup our significant expenses incurred to date and in the future related to the clinical program and the FDA approval process.
